| Summary | The Champion Power Equipment 201323 is a 2500-watt dual fuel inverter generator featuring CO Shield® carbon monoxide auto shutoff system. It operates on gasoline or propane, offering quiet operation at 53 dBA and extended run times. | The Cummins Onan P2500i is a 2200-watt inverter generator built for users who need portable power without sacrificing runtime or noise control. At 48 pounds and measuring 19.8 by 10.5 by 18.3 inches, this unit bridges the gap between true portability and practical capacity. It can run a microwave, small refrigerator, or circular saw continuously, making it suitable for camping trips, job sites, tailgating, and emergency backup. The 1-gallon fuel tank delivers 10 hours at 25 percent load and 8 hours at 50 percent load, meaning most users refuel once per day rather than multiple times.
The inverter topology produces clean power with less than 3 percent THD, which protects laptops, phone chargers, and sensitive electronics from voltage spikes. Cummins backs this unit with a 3-year warranty, longer than the 2.4-year average for comparable inverter generators. The 52 dBA noise level sits between a normal conversation and light traffic, allowing operation in noise-restricted campgrounds and residential neighborhoods without drawing complaints. |
